Query builder — Nested rule groups in Lantern's query builder

Lantern’s query builder, shown with a single rule and with nested groups.

The top card holds one rule: a user signup event, marked with the Salesforce icon, higher than a set number, followed by Add rule, Add inner group and Run Query. The bottom card shows the nesting. A top-level rule joins an inner group with And, and inside that group the conditions mix comparison operators (= and <) with a change check: active users has changed.

Every row keeps the same order (drag handle, attribute, operator, value, delete), so even a long query reads line by line.
